The flood in 2020 caused significant damage to the Swan Lake Trading Post, disrupting operations and requiring extensive repairs. The flooding was triggered by a fallen tree blocking a creek during spring runoff, leading to water overrunning its banks and entering the store. The incident highlights the risks of seasonal flooding in remote areas like Swan Lake, Montana. While the remodel has ensured the trading post's survival, such events underscore the importance of preparedness for natural disasters in rural communities.
